Definitions

  • Basic melting fluxes for submerged arc welding have better mechanical properties than acidic welding fluxes and are therefore being used more and more frequently.
  • the amount of alkalies and alkaline earth metals in the fluxes becomes higher and this leads, in general, to higher hygroscopicity.
  • Agglomerated fluxes made by mixing and drying or calcining of the finely ground starting components are particularly hygroscopic. That is due partly to the contents in water glass or binder, and partly to their large internal surface.
  • Sintered fluxes too, have a large internal surface and when of appropriately basic character are hygroscopic as well. Moist welding fluxes introduce hydrogen into the goods to be welded, a fact which may lead to crack formation, especially in steel having high strength. In the case of such high strength steels, high notch impact strength is a very valuable property, which is exhibited by basic sintered or agglomorated fluxes. Up to now, the use of fluxes for welding hydrogen sensitive steels failed either because of the moisture content of fluxes, or they had to undergo cumbersome calcining before being used for welding.
  • Molten welding fluxes usually have a dense grain. Their surface is consequently smaller than that of agglomerated or sintered fluxes. For that reason, the absorption of moisture by them is lower than the one exhibited by agglomerated or sintered fluxes of the same composition.
  • the fluxes have too high a content in alkaline earth metals and/or alkalies, and too low a content in acidic or moisture-insensitive components, e.g. SiO 2 , TiO 2 or MnO, they too will absorb moisture from the air.
  • molten basic welding fluxes low in manganese having low moisture sensitivity and good welding properties, can be provided with the following components:
  • compositions Especially good are the following compositions:
  • compositions according to the invention have good seam forming properties, but the welding results with automatic welders having a low open-circuit voltage are in a few cases fluctuating. In some cases many good welds will be produced but then useless welds will for no apparent reason be produced with the same fluxes under identical welding conditions.
  • the alkali chlorides NaCl and/or KCl, or alkaline earth chlorides e.g. CaCl 2 and/or BaCl 2 and/or SrCl 2 and/or MgCl 2 are used.
  • the basic welding fluxes according to the invention made as described are advantageous in other uses of the welding art than submerged arc welding, because of their low moisture sensitivity and their good welding characteristics.
  • the welding fluxes may also be used to advantage in the production of shell masses for electrodes, or as fillers for tubular wire.
  • the percentage to be used in shell masses for electrodes or for fillers of tubular wire depends on the desired final composition of the said articles.
